![]() You will get a notification that the project has been created. Click ‘Choose Template’ button to proceed forward. We have named our project ‘esp32_mac_address.’ For the ESP-IDF board, we have chosen the custom board option. Type ESP-IDF: New Project in the search bar and press enter. Open your VS Code and head over to View > Command Palette. In this section, let’s create an ESP-IDF project to get and set MAC address. Create ESP32 ESP-IDF Project to Set and Get MAC Address However, it is important to note that after each reboot of the ESP32, the MAC address will revert back to its original value and you will need to include a code to set the custom address every time the ESP32 is reset. A MAC address is usually represented as a string of 12 hexadecimal characters separated by colons, for example: 00:11:22:33:44:55.Īlthough MAC addresses are assigned by manufacturers to devices, we can change them to a custom value. ![]() A MAC address is typically assigned by the manufacturer of a device and is stored in the card’s read-only memory (ROM). This use is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth. MAC Address IntroductionĪ MAC address is a unique identifier assigned to each device for use as a network address in communications within a network segment. We will begin by learning how to retrieve the default MAC address and then proceed to change it to a custom value. Setting the custom MAC address of ESP32 becomes very useful in many applications such as enhancing privacy, improving network compatibility, and avoiding address conflicts. In this tutorial, we will learn how to get and set a custom MAC address of ESP32 using ESP-IDF framework.
